WILLIAM H. commw, or new YORK, N. Y., ASSIGNOR TO CHARLES U. BAY, on NEWYORK, N. Y.

SPOOL.

Application filed May 9,

To all whom it may concern:

Be it known that 1, WILLIAM H. CONANT, a citizen of the United States,residing at the city, county, and State of New York, have invented acertain new and useful Improvement in Spools, of which the following isa specification.

This invention relates to improvements in bobbins or spools used forwinding and holding adhesive tape or other flexible material.

Adhesive tape is made in several standard sizes and is generally woundupon spools. By means of my invention the manufacturer is enabled towind an assortment of tapes upon a single spool and to market an articleconvenient for doctors or other persons requiring tapes of variouswidths.

One object of the invention is to provide a spool for carrying aplurality of rolls of material in separated condition.

Another object is to provide a spool upon which a plurality of rolls ofmaterial may be wound without danger of interwinding the adjacent coils.

A further object is to provide a spool with adjustable partitionswhereby several rolls of material of the same or of different widths maybe wound and carried upon a single spool.

WVhile the spool is intended primarily for holding and carrying adhesivetapes of various widths, it is to be understood that I do not limit theinvention with respect to that particular use, as I am aware that myimproved spool may be employed for winding other flexible materials.

In the accompanying drawings illustrating one embodiment of myinvention:

Figure 1 is a side elevation of a spool with a plurality of rolls ofmaterial of different widths wound thereon;

Fig. 2 is a cross-section of the spool; and,

Fig. 3 is a longitudinal section thereof.

Referring now to the drawings, it will be seen that my improved spoolcomprises the usual tubular core or stem 1 having a fixed disk or head 2at each end, the said parts 1924. Serial No. 711,946.

being preferably, though not necessarily, made of metal.

Partition disks 3, preferably of the same size and shape, and preferablymade of the same material as the heads 2, are mounted loosely upon thestem 1 so as to be freely slidable lengthwise thereof. It is preferable,however, that the diameter of the openings in the disks 3 be such as tofit somewhat snugly about the stem 1 so that while the said disks mayslide upon the stem there will be, nevertheless, sufficient frictionalengagement to hold the disks against casual movement when they areplaced in their adjusted positions.

In using the spool, the disks 8 are spaced apart from each other, andfrom the heads, distances substantially corresponding to the widths ofthe tapes or materials t that are intended to be wound upon the spool,and the said material is then wound upon the spool in the usual manner.During the winding operation the disks 3 serve as guides to assureformation of rollshaving flat ends, and, furthermore, where a pluralityof rolls are wound simultaneously the said disks prevent interwinding ofthe coils of the laterally adjacent rolls.

It will be observed that my invention provides means whereby a pluralityof rolls of material of the same or of different widths may be woundupon a single spool in such manner that each roll is completelyseparated from the adjacent ones.

Various modifications in the details of the structure herein describedmay be made without departing from the scope of the invention as definedin the appended claim.

What I claim is:

A spool of the character described comprising a stem having a head ateach end, and a partition member mounted upon and freely slidablelengthwise of the stem but with suficient frictional engagement to holdthe partition member in adjusted position against casual movement.

WILLIAM H. CONANT.
